My invention relates to improvements in Therefrigerator sink unit consists of a rerefrigerators and is more particularly directfrigerator casing 1 having a 'sink 2 posied towards the domestic type of refrigerator tioned upon the top thereof, such refrigerain what is known as a combined refrigerator tor casing having insulated walls and an in- '5 and sink. In this type of unit akitchen sink sulated top 3 which is in proximity to the is positioned upon a refrigerator so as to bottom of the sink, the-skirt 40f the sink sitform a refrigerator sink unit and thus utiting on top of the refrigerator. lize the space beneath the sink which hereto- The waste pipe 5 and its U shaped trap 6 fore in most cases has been more 01: less depends downwardly fromthesink andtherem t d Space; fore must pass into the refrigerator, and as As the waste pipe with its U shaped trap lllustrated in Fig. 2 I have shown such waste must necessarily depend downwardly from plpe extending through horizontal and-verthe sink into the refrigerator, the object of tical slots 7 and 8 in the top and back of my invention is to furnish a suitable waste the refrlgerator casing, such slots opening waste pipe from the refrigerator, and in shaped slot. p which such casing maybe readily removed It w ll be readily apparent that ifthe to leave the waste pipe conveniently acces- Waste plpe were not effectively insulated from ibl I r the refrigerator that the cold air in the re- 1 My invention consists of a refrigerator and frigerator would possibly freeze the water in waste pipe casing therefor constructed and the waste pipe trap, 'or onthe other hand arranged all as hereinafter more particularthe passage of hot water through the pipe ly described and illustrated in the accomfrom the sink would radiate heat into the repanying drawing in which frigerator and impalr its efliciency.

The casing wall pipe casing whichiengages the slot in the -construct1on fo1lows standard practice and 5 refrigerator casing as illustrated-in Fig. 2. t the mWlIlg I have shown it formed of as Fig; 4 's also an enlarged vertical cross inner and outer metalsheets B and 14 having sectional view through a vfragmentary porheat lnsulatlng materlal l5 sandwichedtheretion of the refrigerator and waste pipe casbetween.

The central open 4'5 "fling b t nd. 7 portion 19 of the casing 9 receives the waste Fig. :6 IS a perspective view of a fragmenpipe, and when such casing is positioned in tary portion of the wastepipe casing. place the flanges 16 and 17 extend into the Like characters of reference indicate corslots 7 and 8, lying against their sidewalls. jresponding parts'in the different views of The flanges 16 and 17 are of icourseof the same thedrawing;

5 pipe casing which will effectively insulate the into each other to form a substantially L 65 length, or a little shorter, than the slots 7 and 1 If-The casing is then swung upwardly soithat 8, so that the waste pipe casing fits tightly in place with its top face lying against the inner top face of the refrigerator casing, and its back face lying against the back inner face of the refrigerator casing.

The bottom of the central open portion 19 of the casing which consists of the upper'face of the casing bottom 12 is sloped rearwardly as illustrated in Fig. 3, so that any water which might possibly leak from the waste pipe 5 or its trap will'run downwardly-towards the rear wall of the trap casing and go through the slot 8 and down behind-the back of the refrigerator. In order to fur,- ther prevent any such possible leakage passing-into the refrigerator aroundthe back of the waste pipe casing I position a sheet portion 23 which extends betweenthe bottom edges of the back flanges 17 and is furnished :with a downwardly extending lip 24: which extends exteriorly of the rear wall of the refrigerator casing when the waste pipe casing isiin position. It will therefore be read 1ly apparent that any drip from the waste pipe --will run down the bottom of the open portion 19 across the sheetc23, which is acontinuation-ofzsuch bottom, and over the lip 24- out of ,therefrigerator casing.

In order to furnish an air tigh-tclosure between; the waste pipe casing and the re frigerator casing I position a rubber or similarpliable beading 25 extending around the ,slots7 and 8 and against which the top and rear faces ,of 'thewaste pipe casing abut. It .-.willbe understood that my particular construction incorporating an L shapedslot in the refrigerator casing and my waste ,pipecasing extending around such slot .efiectively insulatesthe wastepipe from the lnterior of the refrigerator, and at the SEIXIIB'lHIIlQlGiLVES the waste pipeopen to the free circulation ofQair through. the topslot 7 and the back slot 8;

Forretaining the waste pipecasing in po- .sition, andalso for drawing it tightly in place I have furnished a pair of locking members whichextend. respectively between the front of the waste pipecasing and the top of the refrigerator casing, and between the bottom of ;the waste pipe casing and the inner face of *the refrigerator casing.

Theselocking. members each consist. offa hook 20 which is secured to the refrigerator casing, and. the loop 21 which istcarried by .the waste pipe casing and adapted to engage the book. The loops 21 are swingably mountt ed upon levers 22 intermediately of the length of Lthe levers, such levers being pivotally :mountedupon the waste pipe casing. When theiwaste pipe'casing 1s belngpositioned 1n place the bottoms of the flanges 17 are inserted into the slot r8 so that. the sheet member 23 is. positioned upon the bottom of the slot and'the lip 24'protrudingtherethrough.

the flanges 17 completely enter the slot 8, and the flanges 16 the slot 7 and when this is done the levers 22 are swung towards their respective hooks 20 and the loops 21 positioned upon the hooks. The levers 22 are then swung away from the hooks, thus drawing the loops into tight engagement with the hooks 20 and securing the waste pipe casing tightly in place against the beading 25.

l/Vhen it is desired to remove the casing the levers 22 areswung towards their hooks whichpermits the loops 21 to be disengaged. The casing can then be drawn from about the waste, pipe andby the provision of the rounded ends 18 upon the flanges, the casing can be swung-i downwardly to facilitate removal'without danger; oft-he ends of the flanges jamming against the ,7 ends of; the slot 7.

, From the foregoing description it will :be apparent that ,I'hjave devised a veryc-simple yet effective casing for waste pipes inrefrigerator sink units of the character dQSCribed, which willeifectivelyshield the waste pipe from the refrigerator temperatures and-also shield the refrigeratorfrom the Waste pipe temperatures; and although I have shown and described a particular embodiment of my invention andaparticu-lar form; of attachmentit is to be understood tlmt-Ican change the form of attachment-orrelation of the waste pipe casing to the refrig rator pipe extends into the refrigerator casing, of

a casing surrounding. such projecting: portion of the waste pipe and detachably secured to the refrigerator casing, vand members extending from the casing surrounding I the waste pipe intothe slot in the refrigerator casing.
